In this paper, an optimal channel allocation is developed for a large scale video-on-demand system to allocate transmission resources according to the popularity of videos. In the proposed framework, a video will be delivered to customers through one of the three channels, namely broadcast, multicast, and unicast, depending on whether the video is very hot, hot or cold, respectively. A novel algorithm is developed to allocate appropriate delivery channel for the video according to its popularity so that not only the overall bandwidth of the system is minimized but also a preset quality of service (QoS) is provided for each customer.
